Sheet Metal Hydroforming is similar to the conventional deep-drawing technique, but has significant advantages for the formed part and keeps the tooling costs and production costs low.
Below is the list of t benefits of sheet metal hydroforming, as opposed to the conventional deep-drawing technique.
Hydroforming tooling can cost less than half the price of standard press tooling. Tooling generally required is a male die and a draw ring. The rubber diaphragm typically acts as a universal female die in the sheet metal hydroform machine.
Irregularly contoured shapes are easily formed using hydroforming, it also makes it easy to form irregular shapes and contours because matching dies are not generally needed.
- No Need to Waste Time Thinning Material Out:
No need to waste time stretching. Hydroforming flows the metal rather than stretching it as a result you will have less wall thinning.
- Less Work:
Usually parts require multiple operations with a typical press, with hydroforming most of the operations can be condensed into one operation.
- Save Money:
Since almost all punches and draw rings are made of inexpensive cast iron, hardened tool steels are therefore not often needed. These type of tools carry a longer life span. Sheet metal hydroforming offers a wrapping action of diaphragm which does not cause scuff marks, shock, and stretch lines.
- Quick Set Up:
Tools are able to be mounted easily and quickly they are also self-centering and self aligning. Set-up times are much quicker and very efficient.
- Durability of Materials:
Almost all sheet metals can be hydroformed such as stainless steel, carbon steel, aluminum, copper, brass, precious metals, high strength alloys. The material’s thickness varies within the restrictions of the machine. Usually tool modifications are not required.
